C3 (i). Draw the phasor diagram of an ideal transformer supplying resistive load.
C3 (ii). The primary and secondary winding of an transformer has 90 turns and 50 turns,
respectively. If the primary is connected to 205 V, 50 Hz mains and the maximum flux
density is 2.5 tesla. Calculate (a) the cross-sectional area of the core, and (b) the voltage
induced in Secondary Winding.
The cross sectional area of core is
The voltage induced in Secondary Winding is
C3 (iii). The armature of a 4 pole DC shunt generator has 34 slots and is lap wound with
10 conductors per slots. The shunt field resistance of 52 ohms and an armature
resistance of 2.5 ohms. The flux per pole is 0.04 Wb and each brush drop is 2 V. If the
load resistance of 24 ohms is connected across the armature terminals and the
generator is driven at 845 rpm.
The Armature current is
The power absorbed by the load is
